6/20:San Francisco Giants reliever Sam Dyson was named the closer by Bruce Bochy after Tuesday's win against the Marlins. Will Smith initially started the ninth inning but walked a batter and Dyson was called on to close out the game. Dyson is a must-add while he has the job, but it wouldn't be surprising if his leash is short. Dyson has been known to be streaky in the past, and the Giants have Mark Melancon, Tony Watson and Smith, who are all capable of being the closer as well.--Steve McCarthy - RotoBallerSource: Alex Pavlovic
